To be able to host our City Games, there are two requirements. These are the following:
Tablets or Smartphones
We at GPS Play give our preference to tablets, because of the size of their screens. In this day and age, budget-tablets sporting a 7 or 8 inch screen and costing around €100,- already have a decent 3G/4G Data modem inside. A good example of a budget-tablet with great specifications to host our City Games on is the Archos 70B Helium.
At GPS play we prefer data-subscriptions at KPN or Vodafone, because of their stability. For the size of the data plan you can calculate using a 30MB per game usage.
